Approved and used by Mike Mangini (Dream Theater, Drummer of the Year*), Tempo Advance is the metronome app to bring your musicianship to the next level. Now our exclusive consultant, Mike has been using Tempo Advance since its inception four years ago as a practice tool and an invaluable companion for his Rhythm Knowledge drumming system.

The new Polyrhythm Mode enables concurrent playback of two meters with different beats per measure, synced on the bar. Find out what any combination of up to 20 beats per measure sounds like.

Retaining the hyper-accurate audio engine from our bestselling Tempo, the UI on Tempo Advance has been rethought to focus on the metronome visual cues.

Auto setlist advancement, accelerando, ritardando and playback tracking makes it possible for you to program count-ins or complex songs with varying tempo, time signatures and rhythms.
